METHOD or MAKING TOOLS.

To all whom it may concern: I

-Be it known-that I, Ro Y' H. SMITH, a citizen of the United States,residing vat Kent, in the county of Portage and State of Ohio,haveinvented a certain new and provide a' method by which 'eilicient toolssuch as socket wrenches can be produced in finished jform, quickly andeconomically withregard to time, material, and apparatus requiredfor-their production. Further the invention aims to provide a method bywhich a strong and readilymanipulated' wrench adapted particularly forsetting or "removing rim nuts of a demountable rim automobile wheel, maybe formed inexpensively from small straight iron bar, preferably roundin cross section.

In accordance with. my invention, two substantially parallel shankmembers which maybe parts of the same 'rod,'are subjected to the ;actionof dies and an upsetting tool so as to form a tool head therein, and incarrying out theinvention in the preferred way a rod of suitable lengthand sizeis bent onitself, 'ordoubled, and an integral tool head isformed at the closed end or at the bendbetwe'en the doubled portions,which tool head, in the production. of socket wrenches is formedbyupsetting the closed end of the doubledportion and by. forming awrench socket therein. One or both ends of the rod'mfay be formed intohandle or handles, and for a socket wrench for removing andsettingrimnuts of a demountable rim wheel, the end portions of the. rodare preferably extended laterally from the doubled portionwhich formstheshank of thewr'ench so as toprovideoppositely' projecting handleportions which can be given any shape or bends desired to best adapt itforthe purpose.

' The invention may be briefly summarized asconsisting in the steps ofthe improved method which will be described in the specific'ation andset forth in the appended claims.

One form of the wrench and one way of carrying out the method areillustrated in the accompanying sheet of drawings, whereln-Fig. 1. is aside view being bent in accordance with the first ste of the process toform-a doubled middle portion designed to be formed .into the shank andsocketed head, and the single laterally projecting" handle portions;Fig.

of :a bar after Specification of Letters Patent. i Pate t d Feb 28Application filed October 4,1919. Serial No. 328,500.

2 shows the secondstep of the: process wherein the headis upset onto theend of the doubled shankportion; Fig; 3 is a view showing the third andfinal step er; the process wherein the socket is formed in the upset endor head; tlve view ofthe completed wrench, part of one handle beingbroken away; and Figs. 5 and-6 are sectional views substantially alongthe lines 5+5and 6-6 of Figs. 1. and

Fig. 4 is a perspec 4 4 respectively. Fig. 7 is a View similar-to Fig.2on a reduced scaleshowing a li ht modification, -j r I In carrying outmy inventionin the way that I now regard as themost' satisfactorysuitable-length and eflicient, I start with-"a of a straight barof'iromsteel or other suitable metal,- preferably round incross-sectiomand this bar is bent preferably in the cold, substantiallyin the form shown inFig. l so as to form a doubled'middle":portion l0,and

single laterally or oppositely extendinghandle or manipulating portions11. In other words, the-bar is formed in the shape of a T, with a doubleshanklO which is to form the shank and socketed head of the wrench.

Then the doubled portion 10 isheated to a welding or upsetting heat, andthe heated doubled portion is gripped between a pair of dies such asillustrated at 12 and 13," with the end of the shank portion 10projecting beyond the dies, and then the projecting doubled end of theshank portion 10 is struck by a suitable'upsetting tool such'as shown at141, so as toform a solid annular 4,

head shown M15 in F ig. 3.

Vhen the dies 12 and 13 grip the doubled portion 10, sufficient pressureis preferably exerted to weld the two parts'ormembers of the shank'portion together into a substantially continuous'unitary piece from'thefree doubledend of theshank to a point adj acentt-he point of divergenceof the handle portionsf Q Then the work is placed between dies 16 and17, or between different portions of the same dies asused in thestepillustrated in Fig. 2, with the head 15 formed on the shank of thework set into a recess indicated at 18, and then the head 15 while thuswholly enclosed in the dies, is struck with a socket forming tool 19which imparts a hexagonal, square,'orother suitable shaped socket in thehead, this tool being preferably provided with an annular'shoulderportion 20 which enters the recess 18 and gives a fin'ishto the end ofthe socketed head 15.

This :forms a complete finishedwrench such as illustrated in Fig. 4:,with asocketed head 21 consisting of a continuous solid piece integralwith the parts which heretofore constituted the halves or legs of thedouble shank portion 10, and the latter integrally united, if desired,substantially to the handles 11, though it is not. necessary thattheseparts be welded'together for any considerable extent beyond the-socketed head'21.

e Iii-desired, one of the handles 11 may be provided with ataperedscrew-driver end 22, and the other handle may have its free endportion bent at right angles to, or substantiallyparallel to the shankto facilitate therapid turning of the wrench. The last mentionedfeatures, are, however, immaterial to the present invention,

Above I have described what I regard as the best embodimentof myinvention, but I do not wish to be lconfinedto the precisestepsexplained, for it might be possible to deviateifrom the same tosome extent without departing from the invention ;in its broadestaspects. For example, I have considered using two rods instead of asingle red bent upon itself. These rods could be substantiallybshaped,and in producing a tool from them they would be arranged so thatportions of the rods would be held side by side or inparallelism to formthe shank of the tool, and the other portions extended to form thehandles, and in such case the two shank portions after being heated,would be gripped inthe dies to weld them together, and the tool headwould be upset on the parallel end portions which project from theldies.This I have illustrated on a reduced seale in wherein I have shown thedies as in Fig. 2, and the two rodsat 23 and 24. mounted in the dies 12and 13 as in the preceding views. I do not regard this method asefficient or satisfactory as the preferred method first described.

Thoughmy invention is especially adaptedfor the production of socketwrenches,it might be used to advantage in forming'other tools.
